Which of the following statements is/are correct?a) A whorl of bractiole is called as involucre b) Small and thin bract like structures present on the pedicel are called bractioles c) Sepals are always brightly coloured d) On the thalamus epicalyx is arranged

Bracteoles are correctly defined as small, thin bract-like structures present on the pedicel (flower stalk). An involucre is a whorl of bracts (not bracteoles) typically found at the base of an inflorescence. Sepals are usually green, not brightly colored - that's the role of petals. Epicalyx is indeed arranged on the thalamus, but the question asks which statement is correct, and only (b) is fully accurate.
